Need to Know
The trail is well-marked. Wildlife is active in the area; namely moose and bear. I've seen moose right off the trail several times along the top, and their tracks all over. Make noise and pay attention. There's a pretty cool lookout on the eastern edge of the loop. This trail is growing in popularity and is seeing a lot more traffic; the downhill is great, but be cautious around blind corners.
If you park at the designated parking area, run up past the metal gate and trailhead signage, and up a gravel road for a couple hundred feet. You'll see the marked trail come into the road almost at a switchback angle.
Take this smooth singletrack down a short dip then up, up, up all the way to the "T". The climbs on this loop have some steep/rocky sections that are relatively short. At the T, you can go either way to make a loop back to that point. I highly recommend taking a left at the T and running a clockwise loop. There's still a good amount of climbing to be had from the T in either direction, but this direction allows your downhill to be less interrupted than if you'd gone counter-clockwise, especially if you extend the run out to where Short Ribs comes in.
